title: Concentrations of cefpodoxime in plasma and pleural fluid after a single oral dose of cefpodoxime proxetil.
abstract: Eighteen patients of either sex with pleural effusions underwent aspiration 3, 6 or 12 h after receiving a single oral dose of cefpodoxime proxetil equivalent to 200 mg cefpodoxime. The mean concentrations of cefpodoxime in pleural fluid were, respectively, 0.62, 1.84 and 0.78 mg/l for these three time intervals, the corresponding ratios between pleural fluid and plasma concentrations being 0.24, 0.67 and 1.07. The findings indicate that there is good penetration of cefpodoxime into pleural fluid. Concentrations between 3 and 12 h after dosing were equal to or above the MIC90 for most of the organisms commonly found in lower respiratory tract infections.
